To all whom it mag/concern:

Be it known that I, RUSSEL G1 VVoonWAno,

a citizen of the United States, residingl at lVaulregainin the county of Lake, State of lllinois, have invented certain new and usel ful improvement-s in Presser-Feet for Overseaining Sewing-lilachines, of Which the following is a description, reference being had to the accompanying drawing, and to the let- Yters of reference marked thereon.

My invention relates toen improvement in presser feet, for sewing machines and partieularly to a presser foot adapted to be used upon overseaming machines of the type einF ploying a looper and spreader which cooperate with'a vertically reciprocating needle, the looper threadv being laid over a tongue on the presser foot to give elasticity to the stitch. Such a machine is illustrated in the Union Special single interlock machine, which is Well 'known in the trede. ln

.the-use of such a machine with the ordinary tongned presser foot, it has been found that in sewing very light goods with a very long stitchythe needle thread will pull upout of the goods and also the goods are not properly held down upon the work plate. y l have provided,v therefore, va presser foot which has atongue the under side of which is' lush with the under side of the presser foot, which tongue also extends beneath the part of the presser foot in rear thereof, leaving a clearance between its upper fece and the lower face of the presser foot to allow the threads. to slip oit the tongue. Alsosaid presser foot tongue serves toreduce the usda-l size of the needle opening and prevent any danger of the goods pulling up through said needle hole. The tongue is slightly adjustable laterally to permit the use of di'erent sized threads y The invention therefore, consists in the matters hereinafter described and referred to in' the appended claims.

The invention is'illustrated in the accompanying drawings, in which:

Figure vl is e front elevation of the sewing -inachine embodying my invention, Fig. 2 is a side View of the presser foot showing `also the-needle in relation thereto, Fig. S is a top plan, andvFig-.e a bottom plan View of the presser foot. Fig. 5 is a side view of thepresser, foot from the opposite side of Fig. 2, showing the tongue detached.. Fig. 6 is a similar View' showing the tongue in posi- `end the presser foot tion, andig.

This wardly beneath s i ne es nanging edge f or 7 ance between re-ee th and the under ne be on, to allow the tongue.

its nnpersnraee inelineo downwardly toward its .stitchshedding stitc point, shedding1 point extending benen cent body portion the presser v is correspondingly inclined npr, ardlf and extends over said tongue to point aai' where the stitches leid over seid tongue; substantially as described. i

2. s; presser footj its stitch-shedding point, said stitoh-shedding point extending beneath the adjaoent body portion of the presser foot, which is correspondingly inclined upwardly and which is also inclined to the longitudinal axis of said tongue.

3. A presser toot having s out out por tion at one side thereof, and a. recess in its upper surface, a stitch supporting tongue said having a shank mounted in said recess,

stitch supporting tongue having its lower flush with thefbearing foot and its upper y surface inclined downwardly toward its?I face substantially -;-:uri"iceV of the presser l stitch shedding point; substzintially as del scribed.

d. A presser foot having s'cut out porl tion at one side thereof, and a recess in its l upper surface, a stitch supporting tongue l having a shank mounted in seid recess, means whereby said tongue may be adjusted, said stitch supporting tongue having its lower face substantially lush with the beering surface of the presser foot and its uper surface inclined downwardly toward its stitch shedding point; substantially as described.

In testimony whereof I allix niy signature, -in presence o two witnesses.
